That is, when this card processing device connection signal is not input, the reel drive motors 7L, 7C, and 7R are not driven and controlled, and coins are not lent even if the lending button 71 is pressed. Immobilize the game by doing. A predetermined DC current is supplied from the power supply circuit 62 to the various devices and control circuits described above. Also, RA
The M48 is configured to be supplied with a current from the backup power supply 63 for holding a memory, and even if the current supply from the power supply circuit 62 is stopped due to a power failure or the like, the probability setting value and the game state are set to a predetermined value. It is configured so that it can be stored for a period.

FIGS. 6 to 9 and FIGS. 12 to 17 are
6 is a flowchart for explaining the operation of the control circuit shown in FIG.

FIG. 6A shows a processing program executed when the power is turned on. Turning on the power of the slot machine is performed at the beginning of business at the amusement hall, or at the time of business such as when the power is once shut down due to a power failure during the amusement hall operation and the power is restored again. Can be considered. In FIG. 6, first, in step S (hereinafter referred to as S) 1, it is determined whether or not the reset switch is ON. The reset switch 4 is used to select whether to set the game over (stop) to function or not to function. If the reset switch 4 is ON, the game is over from S3. The mode is set to nothing and the game over (stop) is set not to function. On the other hand, if the reset switch 4 is turned off, the game over mode is set in S2 and the game over (stop) is set. The presence / absence of the stop may be set with a dedicated switch. Next, in S4, it is determined whether or not the key switch is ON. When the key switch 43 is ON, it is in the probability setting mode and the key switch 43 is OF.
If it is F, it means that the game mode is set. If the key switch is OFF, proceed to S5 and R
It is determined whether the AM is normal, and if the AM is normal, the slot machine returns to the game state when the power was cut off. That is, since the RAM 48 shown in FIG. 4 is backed up by the backup power supply 63 at the time of a power failure or the like, the RAM 48 is executed at the time of the power supply falling such as the time of the power failure in the steps of S33 to S200 described later. The RAM 48 stores the steps of the program, and if YES is determined in S5, the program control is returned to the stored step when the power is cut off.

On the other hand, when the program is out of control,
A NO determination is made in S5 and the process proceeds to S6, in which the RAM is initialized and the winning probability setting value is initialized. The initialization of the winning probability in S6 is initialized to the set value "3", for example. As will be described later, the set values are prepared in 6 steps from the lowest probability "1" to the highest probability "6", and with the initialization by S6, the average probability is almost equal. It is initialized to a certain "3". As a result, when the slot machine is initialized due to program runaway, etc., it is set to an almost average probability, so the winning probability is extremely high after initialization due to program runaway etc. There is an advantage that it is possible to prevent an extreme change such as switching to or switching to an extremely low set value.

On the other hand, when the key switch 43 is ON, that is, when the probability setting mode is operated, the process proceeds to S7, and the inserted coin flow path is switched to the return side so that the inserted coin is returned. Next, the process proceeds to S8, and it is determined whether or not there is a start operation. If not, the process proceeds to S10. In S10, it is determined whether or not the door switch is operated. If not, the set value of the probability at the present time is displayed in, for example, the payout amount display 27 in S13, and S8 is displayed.
Return to. A dedicated set value indicator may be provided.

During the patrol of S8 to S13, the manager or staff member of the amusement park turns on the door switch 44 (see FIG. 1).
If the operation is repeated, a YES determination is made in S10 and S
In step 11, the probability setting value is incremented by "1". Then S
12A, it is determined whether or not the current set value is "7". Since the upper limit of the set value of this probability is set to "6", when the set value becomes "7", the process proceeds to S12B, the process of setting the set value to "1" is again performed, and the process goes to S13. move on. On the other hand, when the set value is not "7", the process directly proceeds to S13, and the set value at the present time is displayed. The clerk at the game arcade operates the door switch 44 so that the desired set value is obtained while observing the display of the set value of the probability in S13. When the desired set value is reached, the key switch 43 is turned off to switch to the game mode, and then the start lever 12 (see FIG. 1) is operated to turn on the start switch 13 so that S8 is performed.
Therefore, a YES determination is made. As a result, since the key switch 43 has already been turned off, the process proceeds to S14, in which the RAM is initialized, the probability setting value is confirmed, and the setting display is cleared. Next, by S14A, the cumulative number of coins inserted and the total number of coins paid out are set to "100" and "50", respectively, as initial values. This allows
The standard payout rate for small wins during regular games is 50/100
× 100% = 50%. Next, the process proceeds to the game start process.

FIG. 6B is a flow chart showing an interrupt program for the random counter updating process. This Figure 6
The interrupt program shown in (b) is executed based on the pulse signal periodically input from the pulse frequency dividing circuit 53 described above, and is executed once every 4 msec, for example. First, in S15, the value of the random counter R
Is updated by a predetermined number N. Then S1
In step 6, it is judged whether or not the value R of the random counter is equal to or larger than a predetermined maximum value. The decision is made. This one game ends when the display result coins when the variable display device is stopped are not paid out. When the coins are paid out, one game is finished when the coins are paid out. Ends. If one game has not ended, the interrupt program ends as it is, and the next interrupt is awaited.

On the other hand, when the value R of the random counter is greater than or equal to the maximum value, the process proceeds to S17, and after the process of subtracting and updating the value R of the random counter by the maximum value is performed, the process proceeds to S18. Next, if the current interrupt program is executed at the timing when one game ends, S18
Therefore, a YES determination is made and the process proceeds to S19, and the process of changing the value N to be added and updated in S15 is performed based on the value R of the random counter. The addition number N is selected from a plurality of preset prime numbers and a prime number such that the quotient when the maximum value is divided by the prime number does not become an integer, and is changed in S19. By setting the addition number N in this way, the value of the random counter R
Will be in a state in which every value can be taken without exception. Also,
Since the addition number N is changed to another prime number in S19 each time one game is finished, the value R of the random counter becomes a random value, and based on the value of this random counter, it is determined whether or not the prize will be described later. There is the advantage of being able to make random decisions when making them.

FIG. 7A is a flowchart of the interrupt program showing the error check processing. First, S20A
Determines whether or not the card processing device 76 is connected. If the card processing device connection signal is not input, the process proceeds to S20B, and an error code "CC" indicating an error to that effect is displayed on the payout display 27. To be done. If the card processing device 76 is connected, the process proceeds to S20C, and it is determined whether or not there is a shortage of coins to be paid out. If it is determined that the coin is not out, the process proceeds to S21, and it is determined whether or not the inserted coin is jammed. S when the coins are not packed
Proceed to step 22, and the inserted coins are stored in the surplus coin storage tank 41.
(See FIG. 2) It is judged whether or not the coin is full, and if it is not full, the process proceeds to S23 and whether or not the coins paid out from the coin hopper 37 (see FIG. 2) are jammed. If it is not jammed, the process proceeds to S24, it is judged whether or not there is an error, and if it is not in error, the interrupt program ends.

The payout amount, which is the number of coins paid out, does not reach the planned payout amount, which is the number of coins to be paid out as a result of the end of one game, and the coin payout motor 38 is rotating. If the payout of coins is not detected within a certain period of time, it is determined that the coins have run out, and S2
A determination of YES is made by 0C, and the error code "HE" is displayed by the payout amount indicator 27 (see FIG. 1) by S25. On the other hand, the inserted coin is blocked in the coin intake path 35, and the inserted coin sensor 36 (see FIG. 2).
If the coins have been continuously detected for a certain period of time or more, a YES determination is made in S22 and S
The error code "CE" is displayed by 26. Also,
If the inserted coin becomes full in the surplus coin storage tank 41 and the full tank sensor 42 (see FIG. 2) detects full,
A YES determination is made in S22, and the process proceeds to S27, in which the error code "CO" is displayed on the payout amount display 27. When the coins to be paid out from the coin hopper 37 are clogged and the payout coin sensor 39 (see FIG. 2) continuously detects coins for a predetermined time or longer, YES is determined in S23 and the process proceeds to S28. The error code “HJ” is displayed on the payout amount display 27. If a motor error occurs as a result of the determination in S85H described below, a YES determination is made in S23A and the process proceeds to S28A, in which the error code "EE" is displayed by the payout amount display 27. Further, after the error is determined in S20 to S23, the error code is cleared in S24 during the period until the error code is cleared in S32 described later.
A YES determination is made, and the flow proceeds to S29, and the above S2
The display of the error code displayed by any of 5 to S28A continues. In other words, the display of the error code in S29 is continued until the front frame 1B in the open state is closed and the error code is cleared in S32, which will be described later, even after the cause of the error is removed by the attendant of the game arcade. The error code continues to be displayed.

S25, S26, S27, S28, S28
After the process of A or S29 is performed, the process proceeds to S30, where the game of the slot machine is interrupted and an error sound is generated from the speaker 28.

When an attendant at the amusement hall hears that an error sound is being emitted from the speaker 28, the attendant at the amusement hall opens the front frame 1B to remove the cause of the error in the slot machine, and then pays out. The type of error cause that has occurred is identified from the error code displayed by the number display 27, and work is performed according to the type of error cause to eliminate the cause of the error that has occurred. Then, after the work is completed, the staff at the game arcade closes the front frame 1B. Then, the door switch 44 detects that the front frame 1B is closed, and accordingly, the determination of YES is made in S31. As a result, the control proceeds to S32, the error code displayed by the payout amount indicator 27 is cleared, the error sound is stopped, and the game is restarted from the game state at the time of the interruption. The detection output may be derived from the door switch 44 by pressing the door switch 44 with a finger or the like instead of actually closing the front material 1B, and the determination of YES may be made in S31.

FIGS. 7B and 8 are flowcharts showing the game start processing. In S33, the flow path switching solenoid 33 (see FIG. 2) is controlled to switch the flow path of the inserted coin to the take-in side, and the process proceeds to S34, in which it is determined whether or not there is a game switching operation. When there is no game switching operation, the process proceeds to S40, but when the player presses the game switching button 16, S is performed.
35, it is determined whether or not the credit game mode is currently set, and if not, S3
In step 6, the processing for setting the credit game mode is performed. On the other hand, if it is already in the credit game mode, the process proceeds to S37, the coin game mode is performed, the process proceeds to S38, and the credit counter is "0".
Is determined. The credit counter is for counting and storing the number of coins awarded as a prize and the number of coins inserted by the player in the credit game, and S6 will be described later.
0 and S179 add and update by "1" at a time, and S39 and S56 described later subtract and update by "1". If this credit counter is "0", S4
The process proceeds to 0, but if it is "1" or more, the process proceeds to S39, in which one coin is paid out and the credit counter is subtracted and updated by "1", and the process returns to S38. This processing of S39 is repeated until the credit counter becomes "0", and the payout control is performed for the number of coins corresponding to the count value of the credit counter. In other words, when the player switches to the coin game mode while in the credit game mode, coins of the number of coins corresponding to the value of the credit counter additionally stored in the credit game are played by the player. Since it is necessary to pay out to the side, the payout control is performed by this S39. On the other hand, if the player presses the game switch button in the coin game mode at the present time, S3
Proceeding to step 6, the credit game mode is set.

Next, in S40, it is determined whether or not a start operation has been performed, and if the start lever 12 (see FIG. 1) has not been pressed, the operation proceeds to S41A. In S41A, it is determined whether or not there is a coin lending command signal, and if not, the process proceeds to S41H. on the other hand,
When the player presses the lending button 71, an operation signal from the lending switch 72 is input to the card processing device control unit 80, and a coin lending command signal is sent from the card processing device control unit 80 to the control unit 45 of the slot machine 1. Is entered.
Then, the control proceeds to S41B, the coin lending signal is output from the control unit 45 to the card processing device control unit 80, and the lending number is set to "50". On the other hand, the card processing device controller 80 receives this coin lending signal and reduces the value (remaining amount) owned by the player specified by the recorded information of the inserted common card by 1,000 yen. In this embodiment, the coin lending unit is 1000
Although yen is used, the lending unit may be 100 yen, and 100 yen may be deducted for each payout of 5 coins. By performing this process 10 times, 1,000 yen worth of coins may be lent. If you do this, the remaining amount of the common card will be 1
Even if there is a fraction less than 000 yen, you will be able to rent the entire remaining amount.

Next, in S41C, it is judged whether or not the credit game mode is set, and when it is not in the credit game mode, S41F sets
The control of paying out one coin is performed, the process of subtracting “1” from the number of loans is performed, and the process proceeds to S41G. On the other hand, if the player presses the credit operation button 14 to switch the slot machine 1 to the above-mentioned credit game state, YES is determined in S41C, the process proceeds to S41D, and the credit counter becomes "50". Whether or not it is determined. The credit counter is a counter for counting the valuable value (the number of coins, etc.) of the player, which is stored in advance for playing the credit game, and is incremented by "1" by S41D and S60, which will be described later, and then S56. Is subtracted by "1". Then, when the credit counter has reached the upper limit value of "50", the valuable value owned by the player cannot be stored in the credit counter any more, and therefore, the processing proceeds to S41F, and one coin payout control is performed. Be done. On the other hand, the credit counter has an upper limit value of "5.
If it is not "0", the process proceeds to S41E, where "1" is added to the credit counter and the number of loans is "1".
Subtract.

In S41G, it is judged whether or not the number of loans is "0", and if it is not "0", S4.
Returning to 1C, the payout of coins or the addition processing to the credit counter is performed again. By repeating this process, if the number of loans becomes “0”, the process proceeds to S41H.

Next, in S41H, it is determined whether or not the insertion number counter is "3". The number-of-inserts counter is used to count the number of coins inserted by the player through the coin slot 18 in one game or the number of times the player has pressed the credit operation button 14 in the credit game. The number of bets to be bet on the game result is set, and is incremented and updated by "1" by S57 described later, and although not shown, it is cleared in association with S33 at the start of the next game. The number of bets is input and set according to the count value of the throw-in counter, and when the bet number, that is, the count value of the throw-in counter is "1", one valid line (per win line) is set. When the count value is "2", it is set to 3, and when the count value is "3", it is set to 5. The upper limit of the count value of the throw-in counter is set to “3.” If the count value of the throw-in counter is not the upper limit of “3” in S41, the process proceeds to S42 and the bonus game flag is set. Whether or not it is set is determined. The bonus game flag is S162, S169 when the bonus game (regular bonus game) is actually started based on the display result when the variable display device is stopped.
Is set in step S188, and is cleared in step S188 when the bonus game ends. If the bonus game flag is not set, S4
7. If it is set, proceed to S43,
It is determined whether or not the input number counter is "0". If "0", the process proceeds to S47, and if "1" or more, the process proceeds to S44. That is, in the case of the bonus game, since only one effective line of the combination of the variable display devices is effective as described above, only one bet is allowed to be played. Therefore, the insertion number counter is "1". It is controlled so that the value does not exceed. In S44, it is determined whether or not the credit game mode is set, and if it is not the credit game mode, S is set.
Proceeding to 46, after the process of switching the input coin flow path to the return side and returning the coins inserted thereafter, S4 is executed.
Go to 0. On the other hand, if it is in the credit game mode, the process proceeds to S45, and it is judged whether or not the credit counter has already reached its upper limit value of "50". Since the credit counter cannot be updated and updated any more, the process proceeds to S46, in which the inserted coin is returned.

In S47, it is determined whether or not a coin has been inserted, and if so, the process proceeds to S48, in which it is determined whether or not the inserted number counter has already reached its upper limit of "3". If it is already "3", the process proceeds to S60, the process of adding "1" to the credit counter is performed, and the process returns to S40. On the other hand, if the input number counter is not "3", the process proceeds to S49, and it is determined whether or not the bonus game flag is set. If the bonus game flag is not set, the process proceeds to S57. Since there is still a margin in the count value of the input number counter, the process of adding "1" to the count value is performed. If the bonus game flag is set, the process proceeds to S50, and it is determined whether or not the input number counter is "0". In the case of the bonus game, since the upper limit value of the input number counter is "1" as described above, when the input number counter is "1", S6
The process proceeds to 0, and the process of adding "1", which is the number of coins inserted into the credit counter, is performed.
Next, in S58, a process of calling and storing the value R of the random counter that has been added and updated according to the above-described random counter updating process is performed. This random value R
May be stored when it is determined in S40 that the start operation is performed. Next, the process proceeds to S59A, a process of setting the planned payout amount and the payout amount to "0" is performed, and the process proceeds to S59B. The number of coins to be paid out is the number of coins to be paid out to the player according to the type of the prize when the prize is determined based on the display result when the variable display device is stopped. , The number of coins actually paid out based on winning.

In S59B, it is determined whether or not the input number counter is "0", and if it is "0", S59.
Proceeding to C, the effective line corresponding to the number of coins inserted in the previous one game is turned on and the process returns to S40.
On the other hand, if coins have been inserted at the time of executing one game this time, the insertion number counter is not "0", and therefore S5
9D, an effective line corresponding to the input number counter is displayed, and the process returns to S40. The display of this effective line is
If the value of the input counter is "1", the horizontal 1 at the center
Only the effective line display lamps 21 for displaying columns are turned on. When the input number counter is "2", the effective line display lamps 21 and 22 for displaying horizontal three horizontal lines are turned on and the input number counters are " In the case of "3", all of the effective line display lamps 21 to 23 that display five effective lines in three horizontal rows and two diagonally diagonal lines are lit.

Next, if it is determined in S47 that no coin has been inserted, the process proceeds to S51, and it is determined whether the credit counter is "0". If it is not "0", the process proceeds to S52. Then, it is determined whether or not there is a credit operation, and if there is no credit operation, S5.
Proceed to 9B. On the other hand, when the credit counter is "0", the process directly proceeds to S59B without performing the determination in S52. When the credit counter is "0", no matter how much the player presses the credit operation button 14 to perform the credit operation, the game can be played using the count value of the credit counter. This is because it is useless to make a determination as to whether or not a credit operation has been performed because it is not possible. Next, if there is a credit operation, the process proceeds to S53, and it is determined whether or not the insertion number counter is "3". If it is already "3" which is the upper limit value, the credit is given. Ignore the operation and proceed to S59B. On the other hand, if it is not "3", the process proceeds to S54, and it is determined whether or not the bonus game flag is set. If the bonus game flag is set, the process proceeds to S55 and the insertion number counter. Is determined to be "0", and when the input number counter is "1" which is the upper limit value in the bonus game, the credit operation is ignored and the process proceeds to S59B. On the other hand, if the input number counter is "0" or the bonus game flag is not set, the process proceeds to S56, the credit counter is updated by subtracting "1", and then the process proceeds to S57, where "1" is added to the input number counter. Processing is performed.

As described above, every time the player inserts a coin from the coin slot 18 in order to input and set the number of bets to be bet on the game result in one game, the random value R of the random counter is read out in S58. When the player inserts only one coin into the coin insertion slot 18 and starts one game, the random value R read based on the one inserted coin is stored and the random value is stored. Using R, the value-added contents when the variable display device is variable stopped are determined in advance. On the other hand, when the player inserts two coins from the coin insertion slot 18, the random value R read based on the insertion of the first coin is erased and read based on the insertion of the second coin. Updated to the random value R, and the updated random value R is stored. When the player performs a start operation, the stored random value R is used to predetermine the value-added contents when the variable display device is variably stopped. Furthermore, if the player inserts three coins from the coin insertion slot 18, 1
Random value R read based on the insertion of the first coin
Is updated to the random value R read based on the insertion of the second coin, and the updated random value R is updated to the random value R read based on the insertion of the third coin, The finally updated random value R is stored and used for the prior determination of the value-added content when the variable display device is variably stopped. The random value R may be extracted by the start operation. On the other hand, in the credit game, the random value R of the random counter is read out and stored in S58 up to three times each time the player presses the credit operation button 14 to set and input the bet number. The storage of the random value R is similar to the above, if the random value R is read twice,
The random value R read for the first time is updated to the random value R read for the second time and stored, and the random value R is 3
If the random value R is read twice, the random value R read the second time is updated to the random value R read the third time, and the last random value R is stored.

Next, if the player presses the start lever 12, a YES determination is made in S40 and S61
Then, it is judged whether or not the input number counter is "0". If it is "0", the process proceeds to S41, but if it is "1" or more, the process proceeds to S62, and the passage switching solenoid 33 is turned on. The input coin flow path is controlled to switch to the return side, and the subsequent reel rotation control is performed. As a result of the processing in S62, coins inserted thereafter are returned to the coin storage tray 30.

9 and 12 are flow charts showing a program for reel rotation processing. First, in S63, it is determined whether or not one game timer has expired. This one-game timer is for measuring the time (for example, 4.1 seconds) that must be at least elapsed from the start to the end of one game,
It is set by S65. In addition, by changing the time set in one game timer according to the number of bets,
In the case of two bets, a shorter time period than in the case of three bets may be set. If the one-game timer has not expired, the process proceeds to S64, in which a timer end waiting sound is generated from the speaker 28 to notify the player that the one-game timer has not expired. On the other hand, when the one-game timer ends, the process proceeds to S65, the one-game timer is newly set, the operation invalidation timer is set, and the rotation of all reels is started. This operation invalid timer is, as mentioned above,
It is a timer for measuring the time during which the stop buttons 9L, 9C, 9R are invalidated even if they are operated.

Next, in S66, a process for performing a predetermined calculation using the stored random value R is performed. The predetermined calculation means adding, subtracting, multiplying or dividing a random value R by a predetermined value, squaring or squaring the random value R, or substituting the random value R into a predetermined function. Is an operation for calculating the answer.
Next, in S67, the calculation result is calculated as the number of inputs / set value /
A process of comparing with the winning allowance value according to the probability variation counter / small winning combination determination mode is performed.

This winning allowance is, for example, as shown in FIG.
As shown in (c), (d) and FIG. 11, of the big bonus game (BB) winning allowance, the regular bonus game (RB) winning allowance, the re-game winning allowance, and the small win winning allowance. It is composed of four types. The winning allowances are stored in the ROM 47 in the form of a table. The winning allowance shown in FIG. 10 (c) is three bets, the small hand determination mode is “normal”, and the probability fluctuation counter is “0”.
Indicates that the probability setting value is "4". This small winning combination determination mode is set to "normal time" when the value giving situation to the player by the slot machine 1 is higher than the predetermined standard value, and is set to be higher than the standard value. When it is low, it is set to "at the time of high probability" and is used for feedback control of the small winning combination occurrence probability according to the standard value. Also, "at the time of a big bonus"
Is controlled so that a small win occurs with a high probability. The probability variation counter is for storing how many times the probability of occurrence of a big bonus game should be improved, and is set to "2" in S195N described later and to "1" in S195P. When the probability is not improved, "0" is stored. "Probability set value"
Is a value set according to the operation of the key switch described above (see S9 to S13).

As shown in FIG. 10C, if the calculated value in S66 is less than the big bonus winning allowance b ₀ , it corresponds to the big bonus game winning, and if b ₀ or more, the regular bonus game winning allowance b If it is less than ₁ , it corresponds to the regular bonus game, and if it is b ₁ or more and less than the re-game winning allowance value b ₂ , it corresponds to the re-game winning,
If b ₂ or more than 15 pieces of Small Win winning tolerance b ₃ may correspond to small combination winning be paid 15 coins, in the case of 8 pieces of Small Win winning than the permissible value b ₄ in b ₃ or more coins It corresponds to a small win for paying out 8 coins, and a bonus of 6 for small wins for b ₄ or more b ₅
If it is less than, it corresponds to a small win to pay out 6 coins,
In the case of b ₅ less than 3 pieces of Small Win winning tolerance b ₆ above may correspond to a small win prize be paid 3 coins, corresponding to off in the case of more than b _6. Incidentally, FIG. 10 (c), A _34,
B ₃₄ , C ₃₁ , D ₃₁ , E ₃₁ , F ₃₁ , and G ₁₁ are shown in FIG.
The values are shown in (a) and (b). Also, R _MAX is
It is an upper limit value that can be obtained by the calculation result using the random value R.

The numbers 1 to 6 shown in the leftmost column of FIG. 10A indicate probability setting values, and the numbers 1, 2 and 3 shown in the top row indicate coins. The inserted number, that is, the bet number is shown, BB shows a big bonus game, and RB shows a regular bonus game. Further, "normal time" indicates when the probability of occurrence of the big bonus game is in the normal state, and "variable time" indicates when the probability of occurrence of the big bonus game is improved. The numbers 1, 2 and 3 shown in the top row of FIG. 10B indicate the number of coins inserted, that is, the number of bets. "
Indicates whether the small winning combination determination mode is normal, high probability, or big bonus.

In the case of FIG. 10C, three bets are made, the small winning combination determination mode is normal, and the value of the probability variation counter is "0".
Since the probability setting is “4” in FIG.
When the setting of (a) is “4”, the number of inputs is “3”, and the probability of occurrence of the big bonus game is “normal time”, that is, A ₃₄ as the big bonus game winning allowable value, B ₃₄ is used as the regular bonus game winning allowable value. Also, in FIG. 10B, the number of inserted coins is “3” and the small winning combination determination mode is the normal value, that is, the small winning combination allowable value for paying out 15 coins is C _31. , D ₃₁ as a small win winning allowance for paying out 8 coins, E ₃₁ as a small win winning allowance for paying out 6 coins, F ₃₁ as a small win winning allowance for paying out 3 coins
₃₁ , G ₁₁ is used as the re-game winning allowance. The data shown in FIGS. 10A and 10B are stored in the ROM 47 in the form of a table.

FIG. 10 (d) shows a small win determination mode with a three bet.
Is "at high probability" and the value of the probability fluctuation counter is "0"
Indicates that the probability setting value is "4". in this case
According to FIGS. 10 (a) and 10 (b), a big bonus

FIG. 11 (a) is a three-piece bet, small win determination mode.
Is "normal" and the value of the probability fluctuation counter is other than "0"
In the figure, the probability setting value is “4”. This place
In this case, according to FIGS. 10 (a) and 10 (b), the big bower
Sgame winning allowance b₀= A ₄₄, Regular bonus game
Game win allowance b₁= B₀+ B₃₄, Re-game win allowance

Value b_Four= B₃+ D₃₁Allows winning a small winning role of paying out 6 coins
Value b_Five= B_Four+ E₃₁Accepting a small win to pay out 3 coins
Value b₆= B_Five+ F₃₁Becomes

FIG. 11B shows a case where the small winning combination determination mode is “at a high probability”, the value of the probability variation counter is other than “0”, and the probability setting value is “4” in the case of three bets. Is shown in FIG. 11 (b) according to the table of FIG. 10 (a), (b).
As shown in, each winning allowance is set. Figure 11
(C) is a three-piece bet, and the small win determination mode is “at high probability”
The case where the big bonus game winning flag is being set or the regular bonus game winning flag is being set is shown. In this case, there is no allowable value for winning the big bonus game and allowable value for winning the regular bonus. FIG. 11D shows a case where the small winning combination determination mode is “at the time of a big bonus” with a three-bet bet. In this case, there is no allowance value for big bonus and no allowance value for re-game win. In addition, as the bonus game winning allowable value in this case, the numerical value in the bottom line of FIG. 10B is used.

With the above configuration, the small winning combination determination mode is "high probability time" rather than "normal time", the small winning combination occurrence probability is higher, and the small winning combination determination mode is "big bonus". In the case of "time", the probability of a small win is further increased and the probability of a bonus game is also increased. Also,
The probability of big bonus games, the probability of bonus games, the probability of small wins, and the probability of re-games are higher for two bets than one bets and three bets for two bets. Further, the probability of occurrence of the big bonus game is higher when the value of the probability variation counter is other than “0”, than when it is “0”. As shown in FIG. 10A, in this embodiment, when the value of the probability fluctuation counter is not "0" and the probability of occurrence of the big bonus game is improved, the number of coins inserted is three. Limited to 3 bets. By setting the data shown in FIGS. 10 (a) and 10 (b) to appropriate values, a small winning combination payout rate, that is, (each small winning combination winning probability ×
It is possible to set an appropriate value to (coin payout number) / coin inserted number × 100%. For example, 50% when the small winning combination determination mode is "normal", and 10 when "high probability".
Set 0%, 150% at the time of "at the time of big bonus", and so on.

Next, in S68, it is determined whether or not the bonus game flag is set. If the bonus game flag is not set, the process proceeds to S71 and it is determined whether or not the big bonus game flag is set. If it is determined that the big bonus game flag is not set, the process proceeds to S74. At S74, a reel rotating sound is generated from the speaker 28, and then S
In 75, it is determined whether or not the big bonus winning flag or the bonus winning flag is set. If it is already set, the process proceeds to S81. If it is not set, the process proceeds to S76.

In S76, the comparison result in S67,
Whether the calculation result using the random value R is included in the big bonus winning allowable value, that is, 0 ≦ calculation result <b ₀
Is determined, and if it is included, S
Proceeding to 77, the big bonus winning flag is set and proceeding to S80. On the other hand, as a result of the comparison in S67, the calculation result using the random value R is not the big bonus winning allowance value but is included in the bonus winning allowance value (b
_{If 0} ≦ calculation result <b ₁ ), a YES determination is made in S78, the process proceeds to S79, the bonus winning flag is set, and the process proceeds to S80. In S80, the game effect lamp 24
(See FIG. 1) is started, and then S8 is performed.
Go to 5. By the processing of S80, the notification that the big bonus or the bonus is won is given. Note that S8
Instead of turning on the game effect lamp 24 by 0, a dedicated display device may be provided to notify that a big bonus win or a bonus win has occurred, or a predetermined sound is generated from the speaker 28. You may make it notify. As a result of the processing in S80, the player is in a state of recognizing a big bonus win or a bonus win. Since the reach sound is not generated unless the bonus is won (S108 to S110), the player is notified of the reach state even though there is no possibility of becoming a big bonus game or a bonus game. Get rid of discomfort.

When NO is determined in S78, the process proceeds to S81, and it is determined whether or not the comparison result of S67 and the calculation result using the random value R are included in the re-game winning allowable value, and the result is included. If it is not included, the process proceeds to S83. If it is included (b ₁ ≤ operation result <b ₂ ), the process proceeds to S83.
82, the re-game winning flag is set and S85
Proceed to. By setting the re-game winning flag in S82, as will be described later, the variable display device is automatically variably started by a start operation and re-game is controlled without inserting a coin. In S83, S6
It is determined whether or not the comparison result of 7 is the calculation result using the random value R is included in each small win winning allowable value, and if it is not included, the process directly proceeds to S85, but if it is included. (B ₂ ≦ operation result <b ₃ , b ₄ , b ₅ , b ₆ )
In S84, the winning flag corresponding to the type of the small winning combination included is set and the process proceeds to S85.

Next, if the bonus game flag is set, YES is determined in S68 and S
Proceeding to 69, it is judged whether or not the comparison result of S67 and the calculation result of the random value R are included in the JAC winning permissible value. In other words, the determination of YES in S68 means that the game state of the slot machine is in the bonus game, and the display result at the time of variable stop of the variable display device during the bonus game is the stop symbol of "JAC". If so, as described above, a prize is generated during the bonus game, and 15 coins can be paid out, and it is determined in S69 whether or not the prize is generated during the bonus game. Of. Then, if NO is determined in S69, the process directly proceeds to S85, but if YES is determined, S is performed.
Proceeding to 70, the JAC winning flag is set. As a result, as will be described later, control for generating a prize during the bonus game is performed.

On the other hand, if the big bonus game flag is set instead of the bonus game flag, S
If YES is determined by 71, the process proceeds to S72 and S6.
As a result of the comparison by 7, it is determined whether the calculation result using the random value R is included in the bonus game allowable value. When the game state of the slot machine is during the big bonus, the display result when the variable display device is variable stopped is "J
When the combination of the stop symbols of "AC" is achieved, the bonus game in the big bonus game is started as described above. Therefore, in S72, whether or not to generate the bonus game in the big bonus game is determined. That is, the determination is made. And S7
If NO is determined in step 2, the process proceeds to step S83, but if YES is determined, the process proceeds to step S73.
The AC winning flag is set and the process proceeds to S85.

Next, in S85, it is determined whether or not the operation invalidation timer has expired, and the process waits until it expires. The time set in the operation invalidation timer is from S68 to
This is a time (for example, 1 second) longer than the time required to perform the processing of S84. When the operation invalid timer ends, the process proceeds to S86, in which the reel stop timer is set and the operation valid lamps 11L, 11C, 11R (see FIG. 1) are turned on.

Next, in S85A, it is determined whether or not the left reel reference position has been detected. If not detected, the flow proceeds to S85C, where it is determined whether or not the middle reel reference position has been detected and not detected. In this case, the process proceeds to S85E, and it is determined whether or not the right reel reference position is detected. If not, the process proceeds to S85G to determine whether or not the left, middle and right reference position detection flags are set. If it is not set, proceed to S85H,
It is determined whether the operation invalidation timer has expired, and if not, the process returns to S85A. In the middle of the loop of S85A to S85H, the left reel reference position 6
If La is detected by the left reel position sensor 8L, S
Proceeding to 85B, the left reference position detection flag is set.
Further, the middle reel reference position 6Ca is the middle reel position sensor 8
If detected by C, the process proceeds to S85D, and the middle reference position detection flag is set. Also, the right reel reference position 6R
If a is detected by the right reel position sensor 8R, S8
Proceeding to 5F, the right reference position detection flag is set. Then, if all the left, middle, and right reference position detection flags are set, YES is determined in S85G, and S85G is determined.
Proceed to 85I. On the other hand, if the operation invalid timer set in S65 expires without detecting the left, middle, and right reel reference positions, it means that the reel is not rotating or the reel position sensor is out of order. Therefore, a motor error occurs and the operation shifts to the operation when the error occurs.

In S85I, the process waits until the operation invalidation timer expires, and at the end stage, the process proceeds to S86 to validate the reel stop operation. In this way, the stop operation is validated after the operation invalidation timer ends after the reference position of each reel is detected. Further, instead of S85I, it may be determined as in S85J whether or not the number of feeding steps of the stepping motor for rotating the reel has reached a predetermined value, and the process waits until that time, and then proceeds to S86. In S86, the reel stop timer is set, and control is performed to turn on the operation valid lamps 11L, 11C, 11R (see FIG. 1). The reel stop timer is a timer for automatically stopping the reel by measuring a predetermined time when the player has not operated the stop buttons 9L to 9R at all. Next, in S87, it is determined whether or not all reels have stopped. If not, the process proceeds to S88, in which it is determined whether or not the reel stop timer has expired. If it is determined that the reel stop timer has expired, the process proceeds to S95, the left, middle, and right reel stop flags are set, and the process proceeds to S96. On the other hand, if the reel stop timer has not expired, the process proceeds to S89,
It is judged whether or not there is a left reel stop operation. If not, it is judged in S91 whether or not there is a middle reel stop operation, and if not, it is judged in S93 whether or not there is a right reel stop operation. , If not, S
Proceed to 96. On the other hand, if the player presses the left stop button 9L, YES is determined in S89 and the process proceeds to S90, the left reel stop flag is set and the left reel is stop-controlled. Next, when the player presses the middle stop button 9C, a YES determination is made in S91 and the process proceeds to S92, the middle reel stop flag is set and the middle reel is stop-controlled. If the player presses the right stop button 9R, YES is determined in S93 and the process proceeds to S94 where the right reel stop flag is set and the right reel is stop-controlled. Next, the player pushes each stop button 9L, 9C,
A case where two or more 9Rs are simultaneously pressed will be described.
For example, if the player has a left stop button 9L and a middle stop button 9
If both C and C are pressed at the same time, a YES determination is first made in S89, the left stop flag is set in S90, the left reel is stopped and controlled as described later, and a YES determination is made in S91. In S92, the middle reel stop flag is set and the middle reel is stop-controlled as described later. Thus, even if the player presses a plurality of stop buttons at the same time, the reel corresponding to the pressed stop button is stop-controlled, and the stop operation of one of the buttons is invalidated. There is no inconvenience. This is the stop button 9L, 9
The same applies when three C and 9L are pressed at the same time.

Next, in S96, it is determined whether or not the left reel stop flag is set. If not, in S100 it is determined whether or not the middle reel stop flag is set and set. If not, it is determined in S104 whether or not the right reel stop flag is set. If not, the process proceeds to S108. If the left reel stop flag is set, the process proceeds to S97, and it is determined whether or not the left reel is rotating. If it is rotating, S9 is performed.
After the reel stop control is performed by 8, the process proceeds to S99, and the left reel stop flag is cleared. On the other hand, if the left reel has already stopped, a negative determination is made in S97 and the process directly proceeds to S99. Since the same processing as S96 to S99 described for the left reel is performed for the middle reel and the right reel, the repetition of the description is omitted here. Next, when all reels have stopped, S87
Accordingly, a YES determination is made, and the process shifts to the winning determination process shown in FIG.

On the other hand, if NO is determined in S104, the process proceeds to S108, and it is determined whether or not the symbols displayed by any two reels that are stopped are in the reach state. It The reach state is a stage in which any one of the plurality of variable display units 5L, 5C, 5R is still variably displaying, and the display result of the variable display unit that has already stopped is "AAA", "BBB". It means a case where a predetermined display state satisfying a condition that is a combination of specific identification information such as "." Then, if it is determined in S108 that the reach state is not reached, the process proceeds to S87, but if it is determined that the reach state is reached, S109 is performed.
Then, it is judged whether or not the big bonus winning flag or the bonus winning flag is set, and if neither is set, the process proceeds to S87, but if either is set, the process proceeds to S110. , After the reach sound is generated from the speaker 28, the process proceeds to S87.
By producing this reach sound, the player's expectation that the combination of the specific identification information may be established depending on the display result when the variable display portion currently variably displayed by the player is stopped is effective. It can be lively.
In addition to or instead of generating the reach sound from the speaker 28, a display indicating that the reach state is generated may be displayed. Further, the notification at the time of reach may be performed only when the big bonus winning flag is set, or the notification may be performed only at the time of the reach of which one of the winning flags is set.

13 to 15 are S98 and S10.
2 is a flowchart showing specific contents of reel stop control defined by S106. First, in S111, a process of confirming the current symbol number is performed. This symbol number is 0 to 20 (see FIG. 3) as described above.
There is a reel drive motor (stepping motor) 7
L, 7C, 7R feed step number and reel position sensor 8
It is confirmed based on the reference position detection signals of L, 8C and 8R. Next, in S112, it is determined whether or not the bonus game flag is set. If the bonus game flag is set, the process proceeds to S113, and it is determined whether or not the other two reels are stopped. The other two reels mean reels other than the reel for which stop control is currently being performed. And
If the other two reels have not stopped yet, S12
Proceeding to 0, control for stopping the JAC symbol within 4 symbol ahead from the current symbol number confirmed in S111 on the activated valid line is performed, and then proceeds to S152. In the case of a slot machine, in order to prevent the stop control from being unnatural, the player presses the stop buttons 9L, 9C, 9R, which is about 0.2 seconds and is very short. The corresponding reel must be stopped within a predetermined time, and the rotation angle at which the reel can rotate within the very short predetermined time is about four symbols. Therefore, when the stop button is pressed, it is impossible to stop and control the JAC symbols that are 4 symbols or more ahead on the effective line. Therefore, by S120, when there are JAC symbols within 4 symbols ahead. The JAC symbol is controlled to stop on the activated line. Note that FIG.
As shown in, when the current symbol number is not the JAC symbol, the symbol array is configured such that the JAC symbol always exists within the range of 4 symbols ahead of the current symbol number. In this way, when the reel to be stopped at present is not the last reel, it is controlled to stop the JAC symbol on the activated line that is valid regardless of whether the JAC winning flag is set or not. Yes, this allows the player to closely watch the subsequent reel stoppage. Next, the process proceeds to S152, and among the operation valid lamps 11L, 11C, 11R, the operation valid lamp corresponding to the stopped reel is extinguished and the reel stop sound is emitted from the speaker 28.
The process returns to either 103 or S107.

If the bonus game flag is set and the other two reels are stopped, the process proceeds to S104, it is judged whether or not the JAC prize flag is set, and only when it is set, S120 is set. If not set, the process proceeds to S115. S1
In 15, JA within 4 symbol ahead from the current symbol number
The C symbol is removed from the valid line and stopped, and then the process proceeds to S152. In other words, because the JAC winning flag is not set, it is not possible to establish a combination of JAC symbols on the activated effective line, and therefore the JAC symbol is forcibly shifted from the activated effective line. Stop it.

Next, if the bonus game flag is not set, the procedure proceeds to S116, where it is determined whether or not the big bonus game flag is set,
If the BIC bonus game flag is set, the process proceeds to S117, and it is determined whether the JAC winning flag is set. If the JAC winning flag is set, the process proceeds to S118, and another reel is set. A determination is made as to whether or not it is stopped. Then, when the other reels are not stopped, the process proceeds to S120, and similarly to the above, the control for stopping the JAC symbol on the activated effective line is performed. On the other hand, if the other reel is already stopped, the process proceeds to S119, where the current symbol number is 4
JAC of the reel that has stopped the JAC symbol within the symbol tip
Stop on the active line of the AC symbol, stop control is performed so that the combination of JAC symbols is established on the activated effective line, and then the process proceeds to S152.

On the other hand, if the big bonus game flag is not set or if the JAC winning flag is not set, the process proceeds to S121, and it is determined whether or not the re-game winning flag is set. If the re-game winning flag is set, the process proceeds to S122, and it is determined whether or not the other reel is stopped. If the other reel is not yet stopped, S123 is performed.
Go to, JAC within 4 symbols ahead of the current symbol number
It is controlled to align the symbols on the effective line of the stopped JAC symbol and stop, and the process proceeds to S152. On the other hand, if the other reels are stopped, the process proceeds to S124, in which the JAC symbols within the 4 symbol ahead from the current symbol number are aligned and stopped on the effective line of the stopped JAC symbol, and S152 is performed. Proceed to.

On the other hand, if the re-game winning flag is not set, the flow proceeds to S125, where it is determined whether the big bonus winning flag is set. S when the big bonus winning flag is set
In step 126, it is judged whether or not the other reel is stopped, and if the other reel is not stopped yet, S is executed.
Proceeding to 127, it is determined whether or not there is a big bonus symbol (A in this embodiment) within 4 symbols ahead of the current symbol number, and if there is, stop the big bonus symbol on the activated line by S128. After that, the process proceeds to S152. On the other hand, if there is no BIC bonus symbol within 4 symbols ahead of the current symbol number, give up on the start of the BIC bonus game in the current game and proceed to S139. Note that S1
Even when the determination of NO is made by 27, since the BIC bonus winning flag is still set, the control to stop the BIC bonus symbol on the activated line is tried again in the next game. , The trial is repeatedly executed until the big bonus symbol actually stops on the activated line.

Next, if it is determined in S126 that the other reel is stopped, the process proceeds to S129, and it is determined whether or not there is a big bonus symbol on the activated line. If there is, a S130 is performed. It is determined whether or not the BIC bonus symbol that can be stopped on the effective line of the BIC bonus symbol that is stopped is within 4 symbols ahead of the current symbol number, and if there is, the process proceeds to S131, and the BIC bonus symbol is set. Control is performed to stop the reel on the effective line of the big bonus symbol of the reel that is stopped. on the other hand,
In S130, when it is determined that there are no big bonus symbols that can be stopped on the effective line of the stopped big bonus symbol within 4 symbols ahead, give up the start of that big bonus game as described above. In S139, the stop control of the variable display device is attempted so that the big bonus game is started again in the next game.

If the big bonus winning flag is not set, the process proceeds to S132, it is determined whether the bonus winning flag is set, and if the bonus winning flag is set, the process proceeds to S133.
It is determined whether or not the other reels are stopped. When the other reels are not stopped, the process proceeds to S134, and it is determined whether or not there is a bonus symbol (B in this embodiment) within 4 symbols ahead of the current symbol number, and if there is, the process proceeds to S135. The control for stopping the bonus symbol on the activated activated line is performed, and the process proceeds to S152.
On the other hand, if it is determined in S134 that there is no bonus symbol, the process proceeds to S152. Next, if it is determined in S133 that another reel is already stopped, S136
Then, it is judged whether or not there is a bonus symbol on the activated line, and if not, the routine proceeds to S139. On the other hand, if there is a bonus symbol on the activated line, the process proceeds to S137, and it is determined whether or not the bonus symbol that can be stopped on the activated line of the stopped bonus symbol is within 4 symbols ahead of the current symbol number. If not, the process proceeds to S139 if there is any, and proceeds to S138 if there is, and the control to stop the bonus symbol on the effective line of the bonus symbol of the reel which is stopped is performed, and the process proceeds to S152.

On the other hand, if it is determined in S132 that the bonus winning flag is not set, the flow proceeds to S139, it is determined whether or not the small winning combination flag is set, and the small winning combination flag is set. If it is determined that the other reels are stopped, it is determined whether or not the other reels are stopped. If the other reels are not yet stopped, the process proceeds to S144. In S144, it is determined whether or not the small winning symbol corresponding to the type of the small winning symbol set is within 4 symbols ahead of the current symbol number, and if not, the process immediately proceeds to S146 to stop the reel immediately. And proceed to S152. On the other hand, if it is determined in S144 that there is a small winning symbol, the process proceeds to S145, and control for stopping the small winning symbol on the activated line is performed and S1 is performed.
Proceed to 52. Next, when another reel is stopped, YES is determined in S140 and the process proceeds to S141.
It is judged whether or not there is a small winning symbol on the activated line,
If not, the process proceeds to S147 if there is, and proceeds to S142 to determine whether or not there is a small winning symbol that can be stopped on the activated line of the small winning symbol which is stopped within 4 symbols ahead of the current symbol number. If there is no, the process proceeds to S147 if there is, proceeds to S143, the control to stop the small winning symbol on the effective line of the small winning symbol of the reel is stopped, and then proceeds to S152.

When it is determined in S139 that the small winning combination flag is not set, the process proceeds to S147. S1
At 47, it is determined whether or not the other two reels are stopped. If the other two reels are not yet stopped, the process proceeds to S149, and it is determined whether or not the reel currently stopped is the left reel. If it is not a reel, stop control is immediately performed in S150, and then the process proceeds to S152, but if it is a left reel, the process proceeds to S151, and stop control is performed so that the single symbol F does not stop on the activated line, and then the process proceeds to S152. In other words, even if it is determined in S139 that the small winning combination flag is not set, if the single symbol F is stopped on the activated line, the small winning combination will be established. Therefore, in S151, the single symbol F is set. It is forced to shift so that it does not stop on the effective line. In addition, when the other two reels are already stopped, S14
When YES is determined by 7, the process proceeds to S148, and the stop control is performed so that all the symbols are not aligned on the activated line, and then the process proceeds to S152. In this way, if there is no winning, the reels stopped at the 1st and 2nd positions are
By detecting the stop operation of the player (S89, S
91, S93) Since it is almost instantly stopped, in the case of a player who is excellent in the technique of operating the stop buttons 9L, 9C, 9R while timing, the reels to be stopped first and second are frequently used. It becomes possible to stop in the reach state. Then, each time a reach sound is generated, it is noisy and annoying, but in this embodiment,
As shown in S109, since the reach sound is generated only when the big bonus and bonus winning flags are set, there is no inconvenience that is offensive to the ears. If the small winning combination flag is set, a process for clearing the small winning combination winning flag is performed at the end of one game (S).
200). Therefore, despite the fact that the winning combination winning flag has been set, it is not possible to align the winning combinations according to the type of the winning combination winning flag on the activated line in the game because of the reel symbol arrangement. In that case, the small win winning flag will be cleared and the small win will be invalidated, so that the small win symbol will be inherited in the next game and the small game symbols will be aligned on the effective line in the next game. There is no control.

A variable display control means for controlling the variable display device is constituted by S63 to S152.

FIG. 16 is a flow chart showing the program of the winning determination process. First, in S153, it is determined whether or not the bonus game flag is set, and if it is not set, the process proceeds to S159, in which it is determined whether or not the big bonus game flag is set and is not set. In this case, the process proceeds to S163, and it is determined whether or not there is a winning on the activated line. If there is no winning on the activated line, the process proceeds to S164, the planned payout amount is set to "0", and then the coin payout control shown in FIG. 16 is performed. On the other hand, if it is determined in S163 that there is a winning on the activated line, S1
Proceeding to 65, the effective line display lamp corresponding to the winning effective line is blinked. When a winning occurs on a plurality of activated lines, the activated winning line is blinked. Next, in S166, it is determined whether or not the prize is a big bonus prize. If it is determined that it is not a big bonus prize, the process proceeds to S168, and it is determined whether or not the prize is a bonus prize. If it is determined that it is not a bonus prize, it is determined in S170 whether it is a re-game prize. Is judged. S170
If it is determined that it is not a re-game prize, the prize is a small winning combination, so the process proceeds to S175, where the planned payout number is set to a value corresponding to the small winning, and then the coin payout process shown in FIG. 17 is performed. .

When it is determined in S166 that the big bonus is won, the process proceeds to S167, each small winning combination determination value is set to the value at the time of big bonus, the big bonus game counter is set to "30", and the bonus number counter is set. Is set to "3", the big bonus winning flag is cleared, the planned payout number is set to "15", the big bonus game flag is set, the game effect lamp is blinked in the first mode, and the big bonus sound is generated. The process of generating from the speaker is performed. This small win win judgment value is set to the value at the time of big bonus, and the number of each small win win judgment value is greatly increased, so the probability of winning each small win is greatly improved, and the big bonus At the time of game, it is controlled with a high probability that the small winning symbols are aligned. During the big bonus game, it is also possible to set a predetermined one of a plurality of types of small winning combination flags for each game without particularly determining whether or not a small winning combination is won. On the other hand, S1
If 68 determines that the bonus is a prize, S
Proceeding to step 169, the bonus game counter is set to “12”, the JAC winning counter is set to “8”, the bonus winning flag is cleared, the planned payout amount is set to “15”, and the bonus game flag is set. The process of blinking the game effect lamp in the second mode and generating the bonus sound from the speaker is performed.

Next, if the bonus game flag is set, a YES determination is made in S153, the flow proceeds to S154, the bonus game counter is decremented by "1", the flow proceeds to S155, and the JAC prize is won on the activated line. It is determined whether or not there is, and if not, the planned payout amount is set to "0" and the coin payout control is performed. On the other hand, if there is a JAC prize on the activated line, S156
Next, the planned payout number is set to "15", the JAC winning counter is decremented by "1", and in S157, the effective line display lamp corresponding to the activated winning line is blinked, and then the coin payout control is performed.

Next, if the BIC bonus game flag is set, a YES determination is made in S159, the process proceeds to S160, the BIC bonus game counter is decremented by "1", and there is a JAC winning on the activated line in S161. Whether or not it is determined, and if not, S163
If there is, proceed to S162. In S162, the bonus game counter is set to "12" and J
The AC prize counter is set to "8", the bonus game flag is set, the planned payout amount is set to "8",
The game effect lamp is made to blink in the second mode, and the bonus sound is generated from the speaker. As described above, S169 is a process performed when the bonus game is started in the normal game that is not the big bonus game, and S1
62 is a process performed when the bonus game is established at the stage when the big bonus game is started.

On the other hand, if it is determined in S170 that the re-game prize has been won, the process proceeds to S171 in which the random value R of the random counter (see FIG. 6) is stored, and the re-game display lamp 64 is displayed in S172. Processing for causing the speaker 28 to generate a re-game sound while lighting or blinking the re-game display is performed. Next, in S173, it is determined whether or not there is a start operation, and the process waits until there is. Then, when the player operates the start lever 12, the control proceeds to S174, and after the re-game winning flag is cleared, the reel rotation process shown in FIG. 9 is performed. As a result, since the reel rotation control is performed without executing the programs shown in FIGS. 7 and 8, the bet number previously input is carried over without the additional input of the bet number being accepted. The game is replayed.

After the expected payout number is set to the small winning combination corresponding value (15, 8, 6 or 3 in FIG. 11) in S175A, the process proceeds to S175B, and it is determined whether or not the bonus game flag is set. If set, the coin payout process shown in FIG. 17 is performed. on the other hand,
If not set, the process proceeds to S175C, and it is determined whether or not the big bonus game flag is set. If it is set, the coin payout control shown in S17 is performed. Then, if the big bonus game flag is not set, the process proceeds to S175E. Note that S175D is a step inserted in the case of another embodiment described later. In S175E, the value of the input number counter is added to the cumulative input number, and the value of the planned payout amount is added to the cumulative output number. Then S175
Proceeding to F, the process of calculating the cumulative payout number / cumulative input number is performed, and the process of calculating the value-giving status by the slot machine 1 is performed.

Next, in S175G, it is determined whether or not the small winning combination determination mode is "high probability time". If not, the processing proceeds to S175H and the calculated value calculated in S175F is 0. It is determined whether or not it is less than 4 (the lower limit value in the normal time), and when it is less than 0.4, the small hand determination mode is set to "at the time of high probability" by S175I, and then the process proceeds to S175L. On the other hand, if the calculated value is 0.4 or more, the process directly proceeds to S175L. S1
As a result of the determination in 75G, if the small winning combination determination mode is “at high probability”, the process proceeds to S175J, and whether or not the calculated value calculated at S175F is 0.5 (upper limit at high probability) or more. Is judged. If it is 0.5 or more, the process proceeds to S175K, the small winning combination determination mode is set to "normal time", and then the process proceeds to S175L. On the other hand, S175
When it is determined by J that the calculated value is less than 0.5, the process directly proceeds to S175L. In this way, when the small winning combination determination mode is normal and the payout rate of the small winning combination falls below 40%, the small winning combination determination mode is updated to "at high probability". Further, when the small win determination mode is "high probability" and the payout rate of the small win reaches 50%, control for returning the small win determination mode to "normal time" is performed.

Next, in S175L, the cumulative number of inputs is "30.
It is determined whether or not it is "0" or more. If it is not, the process proceeds to the coin payout control shown in FIG. 17 as it is. If it is, the process proceeds to S175M to set the cumulative insertion number and the cumulative payment number to 1 respectively. After the process of correcting the value of / 2 (rounding up after the decimal point) is performed, the coin payout control is performed. The processes of S175L and S175M are processes for preventing the cumulative insertion number and the cumulative payout number from becoming too large when the number of games increases.

The method of calculating the payout status of coins, that is, the value-added status is not limited to the embodiment shown in S175F. For example, (cumulative input-cumulative payout) /
The number of games may be calculated. Also, instead of the cumulative payout number of coins, the cumulative payout number may be used,
Alternatively, it may be calculated by using both the cumulative payout number and the cumulative payout number. Further, an addition / subtraction counter that adds according to the number of coins inserted and subtracts according to the number of coins paid out may be provided, and the value of the addition / subtraction counter may be used as the calculated value. In the present embodiment, since the small winning combination occurrence probability is controlled by comparison with the standard value, the random value R of the big bonus and the regular bonus is generated while the payout rate in the normal game is kept within the predetermined range. The game machine is controlled by the extraction timing and the set value, and the high number of times the bonus is not always generated, and the low level is not always the small number, so that the player can continue to enjoy the game. Can be

In the embodiment shown in FIG. 16, when the payout rate is calculated in S175F, the payout rate is calculated based on the number of coins inserted and the number of coins paid out in the normal game except the big bonus game and the regular bonus game. However, instead of that, a big bonus game,
The number of coins inserted and the number of coins paid out in the regular bonus game may be included in the calculation. Also,
Calculation of S175F, determination of S175H, S175J,
It may be performed only when the cumulative number of coins inserted reaches a predetermined value.

Next, another embodiment in which the step of S175D is inserted will be described. In this another embodiment, the probability control of the small winning combination is performed only when three bets are made during the base game. Through S175D, the process proceeds to S175E only when the insertion number counter is "3". The probability control of the winning combination is performed, and when the insertion number counter is not "3", the coin payout control is directly performed. In the case of this another embodiment, the small winning combinations allowance values C ₁₂ , D ₁₂ , E ₁₂ , in the “high probability” column for the coin insertion numbers “1” and “2” in FIG. F ₁₂ , C ₂₂ , D ₂₂ , E ₂₂ , and F ₂₂ are unnecessary. In S175E to S175M, it is calculated by the cumulative value of the input number input by the bet number input means and at least one of the cumulative value of the valuable value and the cumulative value of the valuable value given by the value giving means. Probability control means is configured to compare the value-giving status with a predetermined standard value and control the probability that the display result of the variable display device will be in a specific display mode based on the comparison result.

FIG. 17 is a flowchart showing a coin payout control program. First, in S176, it is determined whether or not the number of payouts reaches the planned number of payouts, and if not, the process proceeds to S177, it is determined whether or not the game mode is the credit game mode, and if it is not the credit game mode. Advances to S180, pays out one coin, advances the payout amount by "1" accordingly, and then returns to S176. On the other hand, if it is in the credit game mode, the process proceeds to S178, and it is determined whether or not the credit counter has reached its upper limit value of "50". If it is, the process proceeds to S180 and payout of coins. If it is not, that is, if there is still room in the credit counter for storage, the process proceeds to S179, the credit counter is incremented by "1", and the payout amount is incremented by "1" in step S176. Return to. This S177
Through the process of S180 are repeatedly executed until the number of payouts = the number of payouts to be paid out, and the payout of coins or addition processing to the credit counter is performed each time, and when the number of payouts reaches the number of payouts to be paid out, the process proceeds to S181. .

In S181, it is determined whether or not the bonus game flag is set. If the bonus game flag is not set, the process proceeds to S182.
It is determined whether or not the big bonus game flag is set, and if the big bonus game flag is not set, the process proceeds to S200, the JAC prize flag is cleared, the small winning combination flag is cleared, and the number of previous insertions. Is updated to the value of the input number counter, the input number counter is cleared, and the process returns to the game start process shown in FIG. 7B. On the other hand, if the bonus game flag is set, the process proceeds to S185, and it is determined whether or not the JAC winning counter is "0". If it is, after the bonus game counter is cleared by S186. , S18
By 8, the JAC winning counter is cleared and the bonus game flag is cleared. On the other hand, if the JAC winning counter is not "0", the process proceeds to S187, it is determined whether the bonus game counter is "0",
If it is "0", the process proceeds to S188, but if it is not "0", the process proceeds to S200, the JAC winning flag is cleared,
The small winning combination flag is cleared and the process returns to the game start process shown in FIG. 7 (b). In this way, the bonus game flag is cleared and the bonus game ends when the bonus game counter reaches “0” or the JAC winning counter reaches “0”.

Next, in S189, it is determined whether or not the big bonus game flag is set. If not set, the game effect lamp 24 is turned off in S190, and the process proceeds to S200. On the other hand, if the big bonus game flag is set, the process proceeds to S191 and the bonus counter is set to "1".
The process of decrementing is performed, and in S192, it is determined whether or not the bonus counter is "0". When the bonus counter is not "0", the process proceeds to S193, the game effect lamp is blinked in the first mode, and the big bonus sound is generated from the speaker 28, and the process proceeds to S200. On the other hand, if the bonus number counter is "0", the process proceeds to S194, and after clearing the big bonus game counter, S1 is performed.
Proceed to 95.

On the other hand, when the bonus game flag is not set and the big bonus game flag is set, the process proceeds to S183, and it is judged whether or not the big bonus game counter is "0".
If it is not "0", the process proceeds to S200, but if it is "0", the process proceeds to S184, a process of clearing the bonus number counter is performed, and the process proceeds to S195A. In S195A, the big bonus game flag is cleared to end the big bonus game, the small winning combination determination mode is set to "normal time", the cumulative insertion number is set to "100", the cumulative payout number is set to "50", and the game effect is obtained. Processing for turning off the lamp is performed. In other words, the big bonus game ends when the big bonus game counter reaches "0" or when the bonus number counter reaches "0", and since it becomes a normal game thereafter, the small role winning determination mode Is returned to the "normal time", and the cumulative input number and the cumulative payout number are returned to the initial values (see S14A).

Next, in S195B, a process of storing the random value R at the present time is performed, and in S195C, a process of performing a predetermined calculation using the stored value is performed. The predetermined operation is, for example, subtraction, addition, multiplication, division of a predetermined numerical value from the stored random value R, squaring or cubed of the random value R, or random It is an operation such as substituting the value R into a predetermined function to calculate an answer. Then S195D
Then, the processing of comparing the calculation result with the probability variation winning permissible value is performed. The probability variation winning allowance value is an allowance value that can improve the probability of occurrence of a big bonus game. Two types of probability variation win allowance values are defined: a probability variation twice win allowance value that causes a probability fluctuation state twice, and a probability fluctuation one win allowance value that causes a probability fluctuation state only once. . If the calculation result is within the range of the probability variation twice-winning permissible value by S195E, S
Proceeding to 195F, the number of games / variable display 25 scheduled stop symbol is set to "77".
Go to 5J. On the other hand, if the calculation result is within the range of the probability variation once-winning permissible value, NO is determined in S195E and YES is determined in S195G.
Proceeding to 195H, the process of setting the scheduled stop symbol of the number-of-games / variable display 25 to "33" is performed and S195 is executed.
Go to J. On the other hand, if the calculation result is neither within the range of the probability variation twice-winning permissible value nor within the range of the probability variation once-winning permissible value, the process proceeds to S195I, and the scheduled stop symbol of the game number / variable display 25 is displayed. A process of setting a falling stop design is performed.

Next, in S195J, the timer for variably displaying the number-of-games / variable display 25 is set, and the variable display is controlled to start. Next, proceeding to S195K, it is judged whether or not the set timer has expired, and it waits until it expires and continues to variably display the number-of-games / variable display 25. Then, when the timer expires, the process proceeds to S195L, and the game number / variable display 25
The stop control is performed so that the stop symbol set by S195F, 195H, or 195I is obtained. Next, proceeding to S195M, it is judged whether or not a special gaming state in which the stop symbol is "77" has occurred, and "77"
If so, the process proceeds to S195N, the probability variation counter is set to "2", and the process proceeds to S195Q.
On the other hand, when the special game state in which the stop symbol is "33" has occurred, the determination of YES is made by S195O and the process proceeds to S195P, and the process of setting the probability variation counter to "1" is made and S195Q. Proceed to. If the stop symbol is a detached symbol, S195N, S195
P processing is not performed. Next, proceeding to S195Q, it is determined whether or not the value of the probability variation counter is "0". If it is "0", proceeding to S196, but if not "0" proceeding to S195R, game effect. After the lamp is blinked in the third mode to display to the player that the probability of big bonus game occurrence is in the probability variation state, S19
Go to 6. The step of S195S may be inserted after this S195R. This S195S is a process of setting the small winning combination determination mode to "at high probability". As a result, when the probability variation counter is not "0", the small winning combination determination mode is set to "at high probability". By performing the processing of S175 and S195S, when the probability changes, the big bonus winning probability is improved and the small win payout rate at the time of "high probability" is 100% (so-called equal return). You can play the game without losing coins until you win.
In this embodiment, a variable display for randomly displaying whether or not to change the probability is used as a variable display for displaying the number of games.
Although the variable display 25 is also used, a variable display dedicated to the lottery may be provided. Also, reels 6L, 6C, 6R
You may make it perform a lottery display using. further,
The number of times of probability variation is not limited to two types, and may be one type or three or more types. Also, instead of or in addition to changing the probability change frequency, the winning probability at the time of probability change may be changed. In addition, in S195N and S195P, the process of setting the probability variation counter to "2" and "1" is performed, but instead, +2 and +1 are performed each time these steps are executed. Good. If the probability variation counter is not "0", the winning may be invalidated or the lottery may not be performed.

Furthermore, the lottery timing of whether or not the probability change is performed is not limited to the example. For example, when the big bonus is won, when the big bonus occurs, when the big bonus game ends, the next game occurs, when a specific small win occurs, when the game replays, when the bonus is won, when the bonus occurs, the next game after the bonus game ends, etc. May be the time. A value that gives a predetermined value when the display result of the variable display device is in a predetermined specific display mode by S176 to S200, the coin hopper 37, the coin payout motor 38, and the payout coin sensor 39. The giving means is configured. In addition, the S195B through S
195P, S77A, S77B, S67, FIG.
According to the table data shown in (a), (b), and FIGS. 11 (a) and (b), when the gaming state of the gaming machine becomes a predetermined special gaming state, the variable display device Probability variation control means is configured to vary the probability that the display result will be in the specific display mode.

Next, in S196, it is determined whether or not the game is over. If the reset switch 4 is turned on when the power is turned on, the game is not set as described above (S3
If the reset switch 4 is turned off, the game over is set as described above (see S2). By S196, it is determined whether or not the game is over. Is S2
00, the process returns to the game start shown in FIG. 7B, and the game start process is started. On the other hand, if it is determined that the game is over, the process proceeds to S197, where the code “OF” is displayed on the payout amount display 27 and the game over sound is generated from the speaker 28. As a result, the game of the slot machine is over (stopped). Then, the process proceeds to S198, it is determined whether or not there is a reset operation, and S1
The processing of 97 is continued. Then, when the attendant of the game arcade inserts a predetermined key into the reset keyhole 3b and operates the reset switch 4, a YES determination is made in S198 and the process proceeds to S199, where the code display of "OF" is cleared, After the game over sound is stopped, the process proceeds to S200.
With this configuration, depending on the business mode of the amusement hall, when the slot machine reaches the stopped state, the prize exchange is performed every time the slot machine reaches the stopped state. On the other hand, even if the slot machine reaches the stopped state, in the amusement hall that employs the so-called non-quantitative system that continues the game without exchanging the prize, the stop selection means Therefore, the stopping means may be selected so as not to function.

The following is another method for controlling the stop of the slot machine in accordance with the business mode of the game hall.

After the processing of S195 shown in FIG. 17, for example, the timer for automatic reset is set, then the processing of displaying the code "OF" and generating the game over sound is performed, and then the presence or absence of the game over is checked. Prepare a step to judge. If it is determined that the game is not over, the process proceeds to a step of determining whether or not the automatic reset timer has expired, and if the timer has not expired, the code "OF" is displayed again and Return to the step of generating the game over sound. Then, at the stage when the timer for automatic reset has expired, the process of clearing the code display and stopping the game over sound is executed, and then the process returns to S200 shown in FIG. On the other hand, when it is determined that the game is over in the step of determining whether or not the game is over, the process proceeds to the step of determining whether or not the reset operation is performed. When it is determined that the reset operation is not performed, the code "OF" is displayed and the process returns to the process of generating the game over sound. When it is determined that the reset operation is performed, the process proceeds to the process of clearing the code display and stopping the game over sound, and then proceeds to S200 of FIG.

That is, if the game is not set to be over in S1 to S3, wait for the automatic reset timer to expire, and at the end, display a code indicating that the game is over automatically. When the game over sound is cleared to return to the game start processing and the game over processing is set, the code indicating the game over is displayed until the reset switch 4 is operated, and the game over sound is emitted. Try to keep the stoppage condition generated from the speaker. Further, the step of determining whether or not there is a reset operation and the processing step of clearing the code display and stopping the game over sound constitute a manual stop canceling means for canceling stop by manual operation. There is.
Further, S1 to S3 constitute a stop release mode selection means for selecting either one of the stop release by the automatic stop release means and the stop release by the manual stop release means. According to this another embodiment, when the game is in the no game over mode, once the big bonus game is over, the game is over (stopped state), and the game is automatically over after a predetermined time elapses. Since the game is released, the game is not played for the predetermined time when the game is over. As a result, from the game over cancellation to the next game over or big after separating the game over state in which no game is played when the profit information such as inserted coins and the disadvantage information such as prize coins are aggregated by the hall management computer. It is also possible to collect information from the start of the bonus game to the game over as one unit.

Although the coins are not lent out from the start of the reel rotation to the end of the coin payout, the coins may be lendable at all times. Further, the present invention may be a slot machine of a type in which a pachinko ball is used instead of a coin to play a game. In that case, the bet number input means detects the number of pachinko balls inserted by the player as the bet number. Further, a slot machine may be used in which a recording medium such as a card is inserted and a game is played by using the valuable value owned by the player specified by the recorded information of the recording medium. In this case, the operation detecting means for detecting the operation of the player for using a part of the valuable value owned by the player as the bet number serves as the bet number input means. further,
The variable display device may be automatically stopped after a predetermined time elapses without the stop button, or the variable display device may be variably started by inputting the bet number without the start lever. A value that gives a predetermined value when the display result of the variable display device is in a predetermined specific display mode by S176 to S200, the coin hopper 37, the coin payout motor 38, and the payout coin sensor 39. The giving means is configured. The value adding means may be, for example, a payout of a pachinko ball or a payout of a recording medium recording the score at the end of the game, instead of paying out a coin as a prize. In addition, the variable display device is a device for variably displaying a design by an electric display device including a CRT, a liquid crystal, an LED, an electroluminescence, or a plurality of discs on which the design is drawn, instead of the rotary reel type. Any type of variable display device may be used, such as one that rotates and variably displays, one that moves a belt on which a pattern is drawn, or a so-called leaf type. Further, the number of variable display portions is not limited to three.

Another embodiment of the present invention will be described next. (1) As a special game state in which the probability variation start condition is satisfied, when the calculation result of S66 is, for example, part or all of the value within the range of the big bonus winning allowance, the regular bonus winning allowance is allowed. Partial or full value within the range of values, partial or full value within the range of permissible small wins, part or all within the range of re-game winning allowance May occur when the value becomes, and when it becomes a part of the value within the range of deviation.

(2) The special game state may be generated when the big bonus game or the regular bonus game ends in a specific pattern. For example, a case where a bonus game occurs in a specific number of games in a big bonus game, or a JAC winning occurs in a specific number of games in a bonus game can be considered. Further, a special game state may be generated when a combination of the number of games when the bonus game is generated and the number of games when the JAC winning is generated becomes a specific pattern.

(3) A special game state may be generated when the variable display device including the reels 6L, 6C and 6R has a display result which is set to start the probability variation. For example, if a special symbol is provided in the symbol array of the reels and the symbol is stopped on the effective line (hit line), or a part of the symbol combination (for example, “AAB”) that is out of sync with the probability variation start. It is conceivable that the special game state is set when the combination of the symbols is stopped on the effective line (hit line).

(4) A special game state may be set when a big bonus game does not occur for a predetermined period (a predetermined number of games or a predetermined accumulated number of coins). For example, a special game state occurs when neither a big bonus game nor a regular bonus game occurs for a predetermined period, a big bonus game does not occur for a predetermined period, or a regular bonus game occurs a predetermined number of times without a big bonus game occurring for a predetermined period. May be

(5) A special game state may be set when the difference between game machines or the payout rate reaches a predetermined value.
In this case, the difference and the payout rate may be counted from the opening of the game hall, the end of the previous big bonus game, or the change of the probability setting.

(6) When performing the probability variation control, the number of combinations of symbols of the variable display device in which the big bonus game occurs may be increased. With this configuration, when the actual occurrence probability is improved, the display occurrence probability of the variable display device is also improved.

(7) When the probability fluctuation state is reached,
Big Bonus Game Occurrence Only, Regular Bonus Game Occurrence Only, Each Small Win Occurrence Only,
Only the re-game occurrence probability may be variably controlled. Alternatively, the probability variation control may be performed by selecting two or more of the above items. When two or more items are selected and the probability variation is performed, the trigger for the probability variation may be the same or different for each probability variation target.

(8) As a condition for ending the probability fluctuation state, the condition may be ended when the same condition as the starting condition of (1) above is satisfied. In this case, the specific value with which the calculation result of S66 is compared may be the same value as the start condition of (1) or may be a different value.

(9) The probability fluctuation may be ended when the same condition as the probability fluctuation start condition shown in (2) above is satisfied. In that case, the number of games and the specific pattern shown in (2) may be the same as or different from the probability variation start condition. Further, the probability variation state may be ended when a bonus game does not occur in a specific number of big bonus games or when a JAC prize does not occur in a specific number of bonus games. Furthermore, the probability variation state may be terminated when the combination of the number of games in which the bonus game has occurred and the number of games in which the JAC winning has occurred does not have a specific pattern.

(10) The probability variation state may be terminated when the variable display device from the reels 6L, 6C, 6R produces a display result that is determined to terminate the probability variation. Specifically, a special symbol is provided in the symbol array of the reel, and when the symbol is stopped on the activated line, or a part of the combination of symbols that are out of sync is defined as the display result that ends the probability variation, It is possible that the combination of the symbols is stopped on the activated line. In these cases, some of the exclusive symbols and combinations may be the same as or different from the symbols and combinations defined in the starting condition of (3) above. Further, the probability variation state may be terminated when the display result of the regular bonus is generated or when the display result of the specific small win is generated.

(11) The probability fluctuation state may be terminated when a predetermined period of time has passed after the probability fluctuation started. For example, it may be ended when a predetermined number of games has been reached or a predetermined cumulative number of coins has been inserted after the probability fluctuation state has started. Alternatively, the probability variation state may be ended when the winning combination subject to the probability variation control shown in (7) has occurred a predetermined number of times. Furthermore, the probability variation state may be terminated when the earlier condition of either of the above or the above is satisfied.

(12) The probability variation state may be terminated when the difference between the gaming machines and the payout rate reach predetermined values. It is conceivable that the difference number and the payout rate are counted from when the game hall is opened, when the probability setting is changed, or when the probability fluctuation starts.

[0116]

According to the present invention, when the gaming state of the gaming machine becomes a predetermined special gaming state, the probability that the display result of the variable display device becomes a particular display mode varies.
